A novel class of heterogeneous catalysts, containing Group VIII transition metals in combination with alkali organic compounds is prepared, such as potassium naphthalene on ruthenium on carbon. The catalysts are useful as heterogeneous catalysts in the hydrogenation of carboxylic acid esters. A process for producing the materials is described. The catalysts permit the process of the hydrogenation of carboxylic acid esters to primary alcohols to be conducted with the ester in the liquid phase at a temperature not exceeding about 150°C with high selectivity. Catalysts of Group VIII transition metals and alkali metal on carbon are also useful in such processes.
制备了一类新型异相催化剂,含有第八族过渡
金属和碱有机化合物,如碳上
钌上的
萘钾。这些催化剂可用作
羧酸酯氢化过程中的异相催化剂。本文介绍了生产这种材料的工艺。该催化剂可在不超过约 150°C 的温度下,以液相形式将
羧酸酯氢化为伯醇,并具有高选择性。第八族过渡
金属和碳基碱
金属催化剂在此类工艺中也很有用。
